I’ve noticed a couple questions on the forum regarding the creation of controlled vocabularies for OJS3 or at the least changing keyword and subject metadata fields into dropdown menus or selection lists rather than simple free-text fields. OJS3, In fact, doesn’t seem to give us keyword, subject, geography or any other metadata fields when making a submission (or afterward for that matter) free-text or otherwise (besides section, title, abstract and contributors).
We’d really like to add controlled vocabulary to the metadata of each submission. In our cases we are looking for the ability of the author to indicate primary and secondary specializations (two separate dropdown lists) and a selection list allowing the authors to indicate the languages the article focuses on (linguistics journal).
I suspect this is harder to do than it first appears. So I have 3 questions. First, what happened to the subject, keyword, etc. metadata fields with the updgrade from 2.x to 3.x? Second, has anyone successfully created controlled vocabularies as indicated here? Finally, are there future plans to build this functionality into OJS3 in a timeframe that would keep me from trying to develop this on my own?
